Many aspects of gene function can be nicely explained with the one- gene-one-enzyme hypothesis, which states that a gene controls the production of an enzyme. Which of the following findings about gene expression, though, requires an expansion of this simple concept? Non-enzyme proteins are made from genes too. Some genes code for RNA molecules only. Enzymes composed of different polypeptides are coded for by more than one gene. Oa and c, but not b a, b, and c
